JUNNZFF; a citi- 11g at Wylam, '1 and the State of i new useful ;or, of which the es .0 a at or station 1 passage! cars or coaches, ltiou is to bring r the name of topping point.

of. the novel feareioafter set forth, and shown in the it: which:

and the ob and ver breach away, and a car Lw rig shown in dotted lines. h through the Fig. lengthwise through the 1nd right angles to Fig. 2. Fig. 4 is a detail perspective end. View of one of the rollers.

' I flu these drawings A. represents a suitable CSLSLDQI provided with a transparent panel AU Wifltr. this "ca-slug are mounted one above the rollers B and C.

i as mounted upon a-shaft B and bin the roller is a coil spring B which onl to the shaft and the opposite oller or drum B. A flexible sheet nted upon the said. rollers and is from. one roller to the other. s t is the proper position ace to the panel A, 1 provide rolled respectively adjacent the upsides of the panel A and the s over these rollers in winding lug upon and from the drums 'B at D carries'upon its outer stopping places upon. u the order in which they to bring these names camel A. at the proper name in position the i of thus, the following described :scployed:

he (in n G .d upon. its periphery ,as notches belo opposite each s hots 198 the disk is .l. away form shoulders C at 1e notches. A shaft F is r0.-

. dc all per pective View illus-. non 0.: my un em' The roller '33 is we tho had-t l3". and one end of the spring carries a disk (3' tatably mountediu the casing A, and in advance of the drum C and upon this shaft is posite end. of the pawl is adapted to enga e with the notches C A spring G norma y bears upon the said pawl so as to hold one and in en agcment'with one of the said shoulders and hus prevent rotation of the drum 0.

In order that the sheet D may be l'ewound by hand, a handle H is connected to a rojecting end portion of a shaft C upon W ich the drum C is mounted. A cord G is connected to the pawl F and passes loosely through an opening in the front of the casing and by pulling downwardly upon said cord the pawl can be disengaged from the drum so that the same can be readily rotated by the handle H. A bell J is also arranged within the casingand the bell striker is connected by a link J to the pawl F so that actuation of the pawl will sound the bell and thus attract the attention of the passengers when the flexible sheet D is shifted. To shift the sheet automatically the rod F projects from an end of the casingiA and said projecting sufhcient distance from t e track rail to permit a wagon wheel to pass between the plate and the track rail and when the device is used in connection with street cars, I prefer to place the plates L on the side of the intersecting street opposite that upon which the car stops so that after each stop thecar will pass over the plate-L and bring the name of the next street or stopping place into View, and it will be understood that there are as many of the plates L as there arenamesupon the sheet D. I v

While it is not absolutely necessary that the roller 0 be hollow, I prefr to have it-a duplicate of the roller B and mounted upon a shaft D and placed within it a spring D secured at one end to the shaft D and at the opposite end to the rollerQ I also place a In practice I prefer to place the plates L a posite ,end of the lever pointed I by the shoulder 3 'until the roller K? has travele up the incline of the plate L and dro the smaller end of the pawl out of-engagement with its notch C and the rollers B and there has been a one half rotation when the roller K upon the shaftK to prevent wear of the shaft. I I

The operation of the device is as follows: As the roller K comes into contact with the plate L and rides up u on said late, the opwould e depressed, drawing down the rod K and giving a partial rotation to the shaft F5. ihis will throw'the pawl F and will release the larger end of the pawl which has been in engagement with one on the shoulder (L and'wil throw the smaller end of the pawl into the adjacent, notch C andwill at the same time cause the bell J to be sounded. The pawl F having its smaller end lockedin one of the notches C holds the rollers or drums a ainst rotation s from said plate. The dropping of the rol er K and shaft, K will lower the rod K-a-nd artially rotate the shaft F back to its original position throwing C will rotate and unwind the sheet'D until larger end of the awl will be againengaged and the rotation of the rollers B and C will be stopped until the 0 er 'ation is again repeatedat the next plate Having thus fully described my invention,

what clairn and desire to .seeure lay Letters Patent, is

1. A device of the kind described cornprising drums, a flexible sheet winding thereon,

a rotatable rod angled adjacentone end,

means carried by the rod for controlling a step b step movement of the drums, a lever pivota ly mounted upon anaxle of 'alcar, a, rod pivotally connecting the up er end of the said lever with the angled on of the ro'd,

and a wedgeshaped tripping blade adapted to be engaged by the lower end of 'saidlever.

2. A device of the kind describedcor'nprie ing two drur'ns, a flexible sheet windingandunwinding uponsaid drums,' 'rneans for rotatmg. the drums, a disk carried by one drum,-

said disk being cut away upon opposite sides i to form shoulders and having. V -shaped notches between the shoulders, a spring pressed pawl having an end portion to engage the shoulders and an end portion to engage c anismto'actuate' the notches, a tripping me the pawl and means arranged adjacent the car track to actuate the tripping mechanism, as and for the purpose set forth. v
